But I need to figure out precisely where to set the volume control on the preamp for each source, at my desired listening volume, and since I want to listen fairly loudly I don't see how I would avoid having the volume up pretty high at the speakers. I use tests discs for noise source, but I don't think I have a pink noise track at a really, really low level. So, I don't see how measuring at the speakers avoids freaking the cats out. Is there something I am missing? It is immediately obvious that the DAC has quite a bit a higher output than the Touch. Actually I wanted to not have to swap cables last night so I was running DAC into preamp balanced but Touch obviously single ended so very large volume difference between the two. Luckily my Krell preamp has gain switch that changes by 6dB to offset balanced vs not, so I was hoping for a close match using just that, but no such luck. -- ncarver ------------------------------------------------------------------------ ncarver's Profile: http://forums.slimdevices.com/member.php?userid=15905 View this thread: http://forums.slimdevices.com/showthread.php?t=82067 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
